Rated 5 out of 5 by from Royal Pane is the only place I would buy Milgard Windows & Doors!! We have been buying Milgard products from Royal Pane for over 8 years now and wouldn't think of going anywhere else. They are knowledgeable, quick to respond, deliver as promised, and are always available to assist when needed. If you're looking for Milgard products, Royal Pane is the place to go.

Rated 5 out of 5 by from Perfect job! Once again, so happy with Royal Pane’s quality work. After we had our windows done, my parents had their windows done throughout their entire house, and they couldn’t be more pleased with the results. Royal Pane sent several experienced workers who did a beautiful, impeccable job in record time. Several windows were resized. The owner, Jeff Platt, gave excellent guidance with this. It was a tremendous help. His expertise in this area is one of the reasons I chose him originally for the windows and doors in our home. He has a very good eye for this. My parents’ windows look absolutely beautiful inside and out. They can’t believe what a difference it made to their home! Everything was completed exactly the way they wanted. Stucco on all the new construction was again matched to perfection (as it was with our home). I can’t say enough. The team that did the install was truly top notch – such a good group of guys. Hardworking, punctual, great attention to detail, efficient, neat, pleasant, and trustworthy. Everything was always cleaned up well afterwards. They take pride in their work and go above and beyond to make sure everything turns out perfectly. Outstanding product and workmanship at a very fair price. We couldn’t ask for more. We are so very happy with how both jobs turned out and HIGHLY recommend them. Don’t look any further...go with Royal Pane. You’ll be happy you did!

Rated 5 out of 5 by from OUTSTANDING!! From the initial contact with Mona, to meeting with Jeff the owner and Ryan, who provided very helpful ideas and thoroughly explained the installation process, and on through delivery scheduling to the finished product; ABSOLUTELY BEAUTIFUL! Armando, Cory and Drew were very professional installing the windows and cleaning up. The only things they left behind were beautiful windows and very happy customers.

Rated 5 out of 5 by from Excellent!!! I want to thank you and your entire crew for the awesome customer service we received. Especially to the team that completed the demolition and installation, they are hard workers for sure. Your lead man was amazing and creative in the areas that needed specialized detailing. Last but not least I would like you to know that Mona was very patient, informative, and always easy to talk to. I hope you have a restful evening! Kind regards, Maria.

Rated 1 out of 5 by from Not a good experiences with the service I bought and installed the windows and sliding doors. But, when I called for questions and service, never got an response. Then, I emailed, no response either. I don't know why there are so many 5 stars. I am the one singled out? Lucky me!

Rated 5 out of 5 by from Fantastic job! We had our windows and sliding patio door installed by Royal Pane Windows & Doors. The crew did an amazing job. Everything looks fantastic! The crew was very thorough, professional, and took extra care to do a beautiful job on every detail. The stucco on the new construction was matched to perfection. They were efficient as well and cleaned up everything afterwards. Several of our windows needed to be resized and Jeff gave us excellent advice and guidance with that when he came to our home. His expertise and knowledge in this area was a tremendous help. Great experience from start to finish and the pricing was very fair. We couldn’t be more pleased and highly recommend Royal Pane!
